SAFETYCONSIDERATIONS
The precautions listed here are divided into the following two types.
Both cover very important topics, so be sure to follow them carefully.
WARNING
If the warning is not observed, it may cause serious casualties.
CAUTION
If the caution is not observed, it may cause injury or damage to the
equipment.
Warning
■For year round cooling applications with low indoor humidity
conditions, such as Electronic Data Processing rooms, contact
your dealer or see the engineering databook or the service
manual.
■The equipment is not intended for use in a potentially explosive
atmosphere.
■For use of air-conditioning units in applications with temperature
alarm settings it is advised to foresee a delay of 10 minutes for
signalling the alarm in case the alarm temperature is exceeded.
The air-conditioning unit may stop for several minutes during
normal operation for "defrosting of the indoor unit" or when in
"thermostat-stop" operation.
Installation manual
■
Ask your dealer or qualified personnel to carry out installation work
Do not install the machine by yourself.
Improper installation may result in water leakage, electric shocks
or fire.
■Perform installation work in accordance with this installation
manual.
Improper installation may lead to water leakage, electric shocks
or fire.
■Consult your local dealer regarding what to do in case of
refrigerant leakage. When the air conditioner is to be installed in
a small room, it is necessary to take proper measures so that
the amount of any leaked refrigerant does not exceed the
concentration limit in the event of a leakage. Otherwise, this may
lead to an accident due to oxygen depletion.
■Be sure to use only the specified accessories and parts for
installation work.
Failure to use the specified parts may result in water leakage,
electric shocks, fire, or the unit falling.
■Install the air conditioner on a foundation that can withstand its
weight.
Insufficient strength may result in the fall of equipment and
causing injury.
■Carry out the specified installation work in consideration of strong
winds, typhoons, or earthquakes.
Improper installation work may result in accidents due to fall of
equipment.
■Make certain that all electrical work is carried out by qualified
personnel according to the local laws and regulations and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.
■Make sure that all wiring is secure, using the specified wires and
ensuring that external forces do not act on the terminal
connections or wires.
Incomplete connection or fixing may cause a fire.
■When wiring between the indoor and outdoor units, and wiring
the power supply, form the wires so that the frontside panel can
be securely fastened.
If the frontside panel is not in place, overheat of the terminals,
electric shocks or a fire may be caused.
■If refrigerant gas leaks during installation work, ventilate the
area immediately.
To xic gas may be produced if refrigerant gas comes into contact
with fire.
■After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
To xic gas may be produced if refrigerant gas leaks into the room
and comes into contact with a source of fire, such as a fan
heater, stove or cooker.
■Before touching electric terminal parts, turn off power switch.
■Live parts can be easily touched by accident.
Never leave the unit unattended during installation or servicing
when the service panel is removed.
■When planning to relocate former installed units, you must first
recover the refrigerant after the pumping-down operation. Refer
to chapter "Precaution for pumping-down operation" on page 11.
■Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.

Caution
BEFOREINSTALLATION
■Ground the air conditioner.
Grounding resistance should be according to national
regulations
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete grounding may cause electric shocks.
■ Gas pipe.
Ignition or explosion may occur if the gas leaks.
■ Water pipe.
Hard vinyl tubes are not effective grounds.
■ Lightning conductor or telephone ground wire.
Electric potential may rise abnormally if struck by lightning.
■Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may cause electric
shocks and fire.
■Install drain piping according to this installation manual to
ensure good drainage, and insulate the pipe to prevent
condensation.
Improper drain piping may cause water leakage, and make the
furnitures get wet.
■Install the indoor and outdoor units, power wire and connecting
wire at least 1 meter away from televisions or radios to prevent
image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not
be sufficient to eliminate the noise.)
■Do not rinse the outdoor unit. This may cause electric shocks or
fire.
■Do not install the air conditioner in places such as the following:
■ Where there is mist of mineral oil, oil spray or vapour for
example a kitchen.
Plastic parts may deteriorate, and cause them to fall out or
water to leak.
■ Where corrosive gas, such as sulphurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may cause the
refrigerant to leak.
■ Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system, and
cause malfunction of the equipment.
■ Where flammable gases may leak, where carbon fiber or
ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
Such gases may cause a fire.
■ Where the air contains high levels of salt such as that near
the ocean.
■ Where voltage fluctuates a lot, such as that in factories.
■ In vehicles or vessels.
■ Where acidic or alkaline vapour is present.
Since maximum working pressure is 4.0 MPa or 40 bar,
pipes of larger wall thickness may be required. Refer to
paragraph "Selection of piping material" on page 5.
Precautions for R410A
■The refrigerant requires strict cautions for keeping the system
clean, dry and tight.
- Clean and dry
Foreign materials (including mineral oils or moisture) should be
prevented from getting mixed into the system.
- Tight
Read "Precautions on refrigerant piping" on page 6 carefully and
follow these procedures correctly.
■Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant
is in state of gas, its composition changes and the system will
not work properly).
■The connected indoor units must be indoor units designed
exclusively for R410A.
Installation
■For installation of the indoor unit(s), refer to the indoor unit
installation manual.
■Illustrations show class 125 outdoor unit type. Other types also
follow this installation manual.
■This outdoor unit requires the pipe branching kit (optional) when
used as the outdoor unit for the simultaneous operation system.
Refer to catalogues for details.
■Never operate the unit with a damaged or disconnected
discharge thermistor and suction thermistor, burning of the
compressor may result.
■Be sure to confirm the model name and the serial no. of the
outer (front) plates when attaching/detaching the plates to avoid
mistakes.
■When closing the service panels, take care that the tightening
torque does not exceed 4.1 N•m.

Installation shall be done by a licensed refrigeration
technician, the choice of materials and installation shall
comply with the applicable national and international
codes. In Europe, EN378 is the applicable standard that
shall be used.
To persons in charge of piping work:
■Be sure to open the stop valve after piping installing
and vacuming is complete. (Running the system with
the valve closed may break the compressor.)
■It is forbidden to discharge refrigerant into the
atmosphere. Collect the refrigerant in accordance
with the freon collection and destruction law.
■Do not use flux when brazing the refrigerant piping.
For brazing, use phosphor copper brazing filler metal
(BCuP) which does not require a flux.
(If a chlorine flux is used, the piping will corrode, and if
the flux contains fluoride, it will cause the coolant oil to
deteriorate, adversely affecting the coolant piping
system.
Selection of piping material
■Piping and other pressure containing parts shall comply with the
national and international codes and shall be suitable for
refrigerant, use phosphoric acid deoxidised seamless copper for
refrigerant.
■Temper grade: use piping with temper grade in function of the
pipe diameter as listed in table below.
■The pipe thickness of the refrigerant piping should comply with
relevant local and national regulations. The minimal pipe
thickness for R410A piping must be in accordance with the table
below.

Existing or pre-installed piping can be used
1.Piping must comply with the criteria below.
• Pipe diameter must comply with the limitations as indicated in
paragraph "Refrigerant pipe size" on page 5.
• Piping length must be within limits of the allowable piping length
as in paragraph "Allowable pipe length and height difference" on
page 6.
• Piping must be designed for R410A. See paragraph "Selection of
piping material" on page 5.
2.Piping can be reused without cleaning when:
•Total 1-way piping length: <50 m.
• No compressor breakdown has occurred in the history of the unit
to be replaced.
•A correct pump down operation can be executed:
- Operate the unit continuously for 30 minutes in cooling mode.
-Execute a pump down operation.
- Remove the air conditioning units to be replaced.
• Check the contamination inside the existing piping.
If you cannot meet all these requirements, the existing pipes must be
cleaned or replaced after removing the air conditioning units to be
replaced.
3.Prepare the flare connections for higher pressure. See paragraph
"Cautions for flare connection" on page 8.
PRECAUTIONSONREFRIGERANTPIPING
■Do not allow anything other than the designated refrigerant to
get mixed into the freezing cycle, such as air, etc. If any
refrigerant gas leaks while working on the unit, ventilate the
room thoroughly right away.
■Use R410A only when adding refrigerant
Installation tools:
Make sure to use installation tools (gauge manifold charge hose,
etc.) that are exclusively used for R410A installations to
withstand the pressure and to prevent foreign materials (e.g.
mineral oils and moisture) from mixing into the system.
Vacuum pump:
Use a 2-stage vacuum pump with a non-return valve
Make sure the pump oil does not flow oppositely into the system
while the pump is not working.
Use a vacuum pump which can evacuate to –100.7 kPa (5 Torr,
–755 mm Hg).
■During tests never pressurize the appliances with a pressure
higher than the maximum allowable pressure (see unit name
plate: PS).
■In order to prevent dirt, liquid or dust from entering the piping,
cure the piping with a pinch or taping.

■In case of simultaneous operating system
- Upward and downward piping should be performed at the
main piping line.
- Use branch piping kit (optional) for branching refrigerant
pipes.
Precautions to be taken. (For details, refer to the manual attached to
branch piping kit.)
- Install the branch pipes horizontally (with a maximum
inclination of 15°) or vertically.
- Length of branch pipe to the indoor unit should be as short as
possible.
-Try to keep lengths of both branch pipes to the indoor unit
equal.
■When using existing refrigerant piping
Pay attention to the following points when using existing
refrigerant piping
■ Perform a visual check on quality of residual oil in existing
refrigerant piping.
This check is extremely important because using existing
piping with deteriorated oil will cause compressor
breakdown.
- Put some residual oil of the pipes you want to reuse on a
piece of white paper or on the white surface of an oil
checking reference card and compare that oil colour with
the circled colour of the oil checking reference card.
- If oil colour is identical to the circled colour or darker,
replace the piping, install new piping or clean the piping
thoroughly.
- If oil colour is lighter, the pipes can be reused without
cleaning.
An oil checking reference card is indispensable for such
evaluation and can be obtained at your dealer.
■ In the following situations, the existing piping should not be
re-used and new piping should be installed.
- If the previously used model had problems with its
compressor (this might cause oxidised coolant oil, scale
residue and other adverse effects).
- If the indoor or outdoor units were disconnected from the
piping for a long period of time (water or dirt might have
gotten into the piping).
- If copper piping is corroded.
■ Flares should not be re-used but rather new ones made in
order to prevent leaks.
■ Check welded connections for gas leaks, if the local piping
has welded connections.
■ Replace deteriorated insulation with new material.

(Use a metal saw to cut out the slits.)
■To install the connecting pipe to the unit in a downward direction,
make a knockout hole by penetrating the centre area around the
knockout hole using a Ø6 mm drill. (See figure "Field pipes in
four directions".)
■After knocking out the knock-out, it is recommended to apply
repair paint to the edge and the surrounding end surfaces to
prevent rusting.
Preventing foreign objects from entering

■Since the side boards may be deformed if only a torque wrench
is used when loosening or tightening flare nuts, always lock the
stop valve with a wrench and then use a torque wrench.
Do not place wrenches on the valve cover.
1Spanner
2Torque wrench
Applying an excessive torque may distort the interior stop valve
surface causing gas to leak inside the valve and causing the
flare nut to crack eventually.
Do not apply force on the valve cover, this may result in a
refrigerant leak.
■For cooling operation under low ambient temperature or any
other operation under low pressure, apply silicon pad or similar
to prevent freezing of the gas stop valve flare nut (see figure).
Freezing of the flare nut may cause refrigerant leak.
Silicon sealing pad
(Make sure there is no gap)
How to use the stop valve
Use hexagonal wrenches 4 mm and 6 mm.
■Opening the valve
1. Place the hex wrench on the valve bar and turn counter-
clockwise.
2. Stop when the valve bar no longer turns. It is now open.
■Closing the valve
1. Place the hex wrench on the valve bar and turn clockwise.
2. Stop when the valve bar no longer turns. It is now closed.

Cautions for handling the valve cover
Cautions for handling service port
■Always use a flexible charge hose with a push-rod and valve to
enable recovery of remaining refrigerant in the charge hose.
■After the work, tighten the valve cover in place.
Tightening torque: 11.5~13.9 N•m
Precautions when connecting field piping and regarding
insulation
■Be careful not to let the indoor and outdoor branch piping come
into contact with the compressor terminal cover.
If the liquid-side piping insulation might come into contact with it,
adjust the height as shown in the figure below. Also, make sure
the field piping does not touch the bolts or outer panels of the
compressor.
■When the outdoor unit is installed above the indoor unit the
following can occur:
The condensated water on the stop valve can move to the
indoor unit. To avoid this, please cover the stop valve with
sealing material.
■If the temperature is higher than 30°C and the humidity is higher
than RH 80%, then the thickness of the sealing materials should
be at least 20 mm in order to avoid condensation on the surface
of the sealing.
■Be sure to insulate the liquid and gas-side field piping and the
refrigerant branch kit.
Any exposed piping may cause condensation or burns
if touched.
(The highest temperature that the gas-side piping can reach is
around 120°C, so be sure to use insulating material which is
very resistant.)

Cautions for flare connection
■Please refer to the table for the dimensions for processing flares
and for the tightening torques. (Too much tightening will end up
in splitting of the flare.)
If a torque wrench is not available, be aware that the tightening
torque may increase suddenly. Do not tighten nuts any further
than to the angle as listed.

■When connecting the flare nut, coat the flare inner surface with
ether oil or ester oil and initially tighten 3 or 4 turns by hand
before tightening firmly.
■After completing the installation, carry out a gas leak inspection
of the piping connections with nitrogen and such.
Cautions for necessity of a trap
Since there is fear of the oil held inside the riser piping flowing back into
the compressor when stopped and causing liquid compression
phenomenon, or cases of deterioration of oil return, it will be necessary
to provide a trap at an appropriate place in the riser gas piping.

H Install trap at each difference in height of 10 m.
■A trap is not necessary when the outdoor unit is installed in a
higher position than the indoor unit.
EVACUATING
■Do not purge the air with refrigerants. Use a vacuum pump to
vacuum the installation. No additional refrigerant is provided for
air purging.
■Pipes inside the units were checked for leaks by the
manufacturer. The refrigerant pipes fit on site are to be checked
for leaks by the installer.
■Confirm that the valves are firmly closed before leak test or
vacuuming.
2Break the vacuum with a minimum of 2 bar of nitrogen. (Never
pressurize more than 4.0 MPa.)
3Conduct leak test by applying soap water, etc. to the connecting
part of the pipes.

. (No pressure increase
Cautions for brazing
■Be sure to carry out a nitrogen blow when brazing.
Brazing without carrying out nitrogen replacement or releasing
nitrogen into the piping will create large quantities of oxidised
film on the inside of the pipes, adversely affecting valves and
compressors in the refrigerating system and preventing normal
operation. When brazing pipes however, do not use oxidation
preventers. Residue of such preventers may result in choking of
pipes or malfunction of components.
■When brazing while inserting nitrogen into the piping, nitrogen
must be set to 0.02 MPa with a pressure-reducing valve (=just
enough so that it can be felt on the skin).

.
6If the vacuum gauge no longer rises, the stop valves can be
opened.
Following should be executed if there is a possibility of
moisture remaining in the pipe (if piping work is carried out
during the raining season or over a long period of time,
rainwater may enter the pipe during work).
After evacuating the system for 2 hours, pressurize the
system to 0.05 MPa (vacuum break) with nitrogen gas and
evacuate the system again using the vacuum pump for
1 hour to –100.7 kPa (vacuum drying). If the system
cannot be evacuated to –100.7 kPa within 2 hours, repeat
the operation of vacuum break and vacuum drying. Then
after leaving the system in vacuum for 1 hour, confirm that
the vacuum gauge does not rise.
After air purging with a vacuum pump it may happen that
the refrigerant pressure does not rise, not even if the stop
valve is opened. Reason for this phenomenon is the closed
state of for instance the expansion valve in the outdoor unit
circuit, but this is not a problem for running the unit.
(1) Use a 2-stage vacuum pump with a non return valve which
can evacuate to –100.7 kPa (5 Torr, –755 mm Hg).
Evacuate the system from the liquid and gas pipes by using
a vacuum pump for more than 2 hours and bring the system
to –100.7 kPa. After keeping the system under that condition
for more than one hour, check if the vacuum gauge rises or
not. If it rises, the system may either contain moisture inside
or have leaks.

Precaution for servicing
When performing service on the unit requiring the
refrigerant system to be opened, refrigerant must be
evacuated according to local regulations.
This unit requires additional charging of refrigerant according to the
length of pipe connected at the site. Charge the refrigerant to the
liquid pipe in its liquid state through the service port of the liquid stop
valve. Since R410A is a mixed refrigerant, its composition changes if
charged in a state of gas and normal system operation would no
longer be assured.
On this model it is not necessary to charge additionally if the piping
length ≤30 m.
<5 m: See "Total charging weight of the refrigerant (after a leak, etc.)"
on page 11.
Additional charging of refrigerant
■The additional charging amounts relate to the refrigerant piping
length as in "Maximum total one-way piping length" of the table
in paragraph "Allowable pipe length and height difference" on
page 6. (E.g. twin: L1+L2+L3).

ELECTRICALWIRINGWORK
■All field wiring and components must be installed by a
licensed electrician and must comply with relevant
European and national regulations.
■All components procured on the site and all electric
construction should comply with the applicable local
and national codes.
■High voltage
To avoid electrical shock, make sure to disconnect the
power supply 1 minute or more before servicing the
electrical parts. Even after 1 minute, always measure
the voltage at the terminals of main circuit capacitors
or electrical parts and, before touching, make sure
that those voltages are 50 V DC or less.
To persons in charge of electrical wiring work:
Do not operate the unit until the refrigerant piping is
complete. (Running it before the piping is ready will break
the compressor.)
Precautions on electrical wiring work
■Before obtaining access to terminal devices, all supply circuits
must be interrupted.
■Use only copper wires.
■The wiring between the indoor unit and outdoor unit must be for
220~240 V.
■A main switch or other means for disconnection, having a
contact separation in all poles, must be incorporated in the fixed
wiring in accordance with relevant local and national legislation.
Do not turn on the main switch until all the wiring is completed.
■For W1
Make sure to connect power supply cables in normal phase. If
connected in reverse phase, the remote controller of the indoor
unit indicates "U1" and the equipment cannot operate. Change
any two of the three power supply cables (L1, L2, L3) to correct
phase.
If the contact in the magnetic switch should be forcibly turned on
while the equipment is inoperative, the compressor will burn out.
Never try to forcibly turn on the contact.
■Never squeeze bundled cables into a unit.
■Fix cables so that cables do not make contact with the pipes
(especially on high pressure side).
■Secure the electrical wiring with clamping material as shown in
the figure below so that it does not come in contact with the
piping, particularly on the high-pressure side.
Make sure no external pressure is applied to the terminal
connectors.
■When installing the earth leakage breaker make sure that it is
compatible with the inverter (resistant to high frequency
electrical noise) to avoid unnecessary opening of the earth
leakage breaker.
■As this unit is equipped with an inverter, installing a phase
advancing capacitor not only will deteriorate power factor
improvement effect, but also may cause capacitor abnormal
heating accident due to high-frequency waves. Therefore, never
install a phase advancing capacitor.
Secure the wiring in the order shown below.
1Secure the ground wire to the stop valve attachment plate so
that it does not slide.
2Secure the ground wire to the stop valve attachment plate one
more time along with the electric wiring and the inter-unit wiring.
■Lay the electrical wiring so that the front cover does not rise up
when doing wiring work and attach the front cover securely.

indoor unit and remote controller).
■ The fuse on the outdoor unit PCB may have run out.

■If the error code
"L4"
is displayed on the remote controller, it is
possible that air inlet or air outlet are blocked.
■The reversed phase protection detector of this product only
works during the initialisation stage after a power reset.
The reversed phase protection detector is designed to stop the
product in case of an abnormality when the product is started
up.
■ When the reversed phase protection circuit forced the unit to
stop, check if all phases are existing. If this is the case, shut
off the power supply to the unit and replace two of three
phases. Turn on power again and start the unit.
■ Reversed phase detection is not performed while the product
is operating.
■ In case of possible reversal of phases after a momentary
black out of power and the power goes on and off while the
product is operating, install a reversed phase protection
circuit on site. Such situation is not unimaginable when using
generators. Running the product in reversed phase can
break the compressor and other parts.
■For a missing phase in case of W1 units, "E7" or "U2" will be
displayed on the remote controller of the indoor unit.
Operation will be impossible with either one of these
phenomena. If this happens, turn off the power, re-check the
wiring and switch the position of two of the three electrical wires.
(If operation is not possible, do not under any circumstances
force the electromagnetic contactor on.)
Precautions regarding test-runs
1In order to detect stop valves failing to open, operation of the
unit is compulsorily performed in cooling for 2-3 minutes during
the first test run, even if the remote controller was set to heating
operation. In this case, the remote controller will have kept
displaying the heating symbol all the time and the unit will switch
to heating operation automatically after elapse of that time.
2In case you cannot operate the unit in test run mode for any
unusual reason, refer to "Failure diagnosis at the moment of first
installation" on page 14.
3In case you cannot operate the unit in test run mode, the unit
usually returns to its normal state after 30 minutes.
4In case of a wireless remote controller, execute the test run only
after having installed the indoor unit decoration panel with infrared receiver first.
